Granted: 1911-07-20
Abstract: 12,378. Fleming & Ferguson, and Dunlop, E. May 23. [Addition to 10,701/09.] Oil, catching and retaining; dust &c., excluding.-In a bearing for the lower tumbler shaft of bucket dredgers of the kind described in the parent Specification, comprising a bush F in which the tumbler shaft C rotates, a spring- pressed packing-ring H is placed in a recess in the bush to retain oil in the bearing and to exclude water and sand. The ring H bears against the side of the rotating tumbler A, and is provided with packing J to prevent leakage round the back of the ring. The bush F has a flange K, and a cover-plate N, and the two ends of the bucket ladder are connected by a bolt L. In a modification, the flange K and the bolt L are dispensed with, and the cover N is integral with the bush.

Abstract: 19,385. Burns, W. A., and Masson, T. Aug. 30. No Patent granted (Sealing fee not paid). Sights. - Relates to combined open and aperture sights of the kind in which the aperture is used nearer the eye than the open sight. According to the present invention, the sight is either adapted to be mounted on one or other of two beds so designed that, when the sight is in position, the correct scale faces the marksman, or the sight is combined with a swinging arm adapted to occupy two extreme positions and to cooperate with elevating means wnereby a single range scale is sufficient for both positions. In the construction shown in Figs. 1 and 2, one scale is marked at the back of the leaf B and one at the front, and the beds A<0>, Ax are so shaped, as shown in Fig. 2, that, when the sight is transferred from one to the other, it is reversed. In the modification shown in Figs. 5 and 6, the slide B<12> of a lift-up sight is pierced with an aperture B", Fig. 6, and the head B<9>, on which is the open notch, is adapted to fit on the rear bed B<10>, the leaf then being vertical for sighting through the aperture B<11>. By suitably shaping the ramps B<15>, the same scale can serve for both positions. In the construction shown in Fig. 7, the leaf is mounted on an arm B<18> pivoted on a vertical pivot; as in the modification shown in Figs. 1 and 2, one scale is on the front and the other on the back of the leaf. In the construction shown in Figs. 8<a> and 8b, the end of the arm B<18> is so formed that, when in the rear position, an aperture B<21> is presented to the eye as shown in Fig. 8<b>, and when in the front position an open notch B<19>, as shown in Fig. 8<a>. The inclined surfaces A<2>, A<3> engaged by the slider B<20> are so arranged that a single scale serves for both positions.

Abstract: 27,010. Electric and Ordnance Accessories Co., and Etchells, J. Dec. 2. Lighting and heating systems for trains are arranged so that secondary batteries are only connected to the heaters while the dynamo is charging. A solenoid A in circuit with the dynamo completes the heating-circuit from the batteries through contacts A<2>, which re-open when the dynamo current fails. A preliminary heating action may be obtained from the batteries by applying a key to the cam spindle C and raising the contacts by hand, where they are held by a latch B' subsequently released by an electro-magnet B, which becomes energized when current flows from the dynamo. The latch can also be released by hand.

Granted: 1913-06-23
Abstract: 7079. Alston, C. H. T., and Houston, P. T. March 22. [Addition to 3114/11.] Actuating.-In valve apparatus for regulating the supply of steam to the draught tube of a gas-producer and of the kind described in the parent Specification, the supply of steam being dependent upon the temperature of the mixed air and steam, variations of temperature in the air are compensated for. An auxiliary coil m filled with liquid communicates with a diaphragm chamber r, the diaphragm of which is connected by a rod .s with the diaphragm of a chamber k in connexion with a coil f. The steam enters the draught tube a by a nozzle h supplied from a pipe e through a valve c, which is operated by levers l from the rod s. Variation in the air temperature affects both coils m. f, the pressure in one coil opposing the pressure in the other by the action of the opposing diaphragms in the chambers r, k and causing no motion of the lever l<1> and valve c. The auxiliary coil, by resisting the closing of the steam valve c causes a higher temperature to be reached at the main coil f where the temperature of the incoming air is higher, thus maintaining the proportions of steam to air constant.

Title: Improvements in or relating to Electrolysis for use in Electrometallurgy.
Inventor: DEKKER NICOLAS HENRI MARIE
IPC: C25C1/00
Filed: 1912-08-01
Granted: 1913-05-08
Abstract: 17,836. Dekker, N. H. M. Aug. 1. Metals, depositing.-An electrolyte consists of one or more melted hydrated salts, with the addition of just sufficient water to compensate for loss by evaporation. Decomposition of water in the electrolysis, and the formation of basic salts, are thus avoided. In refining metals, salts such as ZnSO4.7H2O and FeSO4.7H2O may be used, and are preferable to solutions of metallic sulphates in fused MgSO4.7H2O. When an insoluble anode is employed, as in the extraction of metals from ores, the electrolyte contains, in addition to the salt of the metal to be extracted, one or more salts such as sodium and magnesium sulphates which do not deposit metals, and is concentrated before electrolysis until no water other than that required for hydration of the salts is left. Acid generated at the insoluble anode is kept out of the cathode electrolyte. Specification 18,488/11, [Class 1 (iii), Oxides &c., Metallic], is referred to.

Title: Improvements in Stabilizers for Aeroplanes.
Inventor: THAW ALEXANDER BLAIR

Filed: 1912-10-29
Granted: 1913-07-24
Abstract: 24,782. Thaw, A. B. Oct. 29. Steering and balancing.-The lateral or longitudinal balancing-members of an aeroplane are actuated by an electric motor which is automatically put into operation by the tilting of the machine. The circuit of the electric motor operating the lateral balancing-planes is interrupted when the tiller of the steering-rudder is turned through a predetermined distance, to prevent the automatic operation of the balancing-planes and allow of banking the machine during turning. In the application of the invention to lateral balance, the cords 20 connected to the ailerons are wound around a drum 23 on a shaft 32. Plates 36, 37 secured to the shaft 32 carry electro-magnets 34, 35, the ends of the windings being connected to insulated rings 38, 39 on the shaft. The magnets are provided with loose cores secured to an armature 56 adapted to engage electro-magnetically with worm-wheels 30, 31 loosely mounted on the shaft 32. The worm-wheels are driven by worms 29 on the shafts of electric motors 27, 26. The circuit of the motor 27 includes a dynamo or accumulator, the electromagnets 34, and leads 42 connected to a pair of contacts 44, Fig. 5, secured to the ends of curved rails 45, Figs. 5 and 6, on which runs a pair of rollers 48 connected by a spindle 49. The circuit of the motor 26 similarly includes the electro-magnets 35 and leads 46 connected to a pair of contacts 47 on the ends of the rails 45 opposite to the contacts 44. When the machine tilts laterally, say to the left, the rollers 48 complete the circuit of the motor 27 and the electro-magnet 34 so that the armature 56 engages with the rotating worm-wheel 30, whereby the drum 23 is turned to actuate the ailerons. The motors may drive the sbaft 32 directly, in which case the electro-magnetic clutches are dispensed with. In another form, two sprocket-wheels loosely mounted on the shaft 32, are continuously driven in opposite directions and are clutched to the shaft 32 by electro-magnets such as 34, 35 when the machine tilts. In order that the automatic lateral balance may be rendered inoperative when the machine is being directed in a sharp curve, the movement of the tiller 63, Fig. 7, operating the rudder through ropes 67, breaks the circuits of the motors 26, 27. For this purpose, the leads 46, 42 of the respective motors are connected to rollers 60, 61 and to contact plates 58, 59 on the tiller 63. The ailerons may also be actuated manually by a cord passing over a drum on a steering-wheel.
